As far as i saw all three versions of him, other than costume, have no real difference, moves seem to be exactly the same among them, too. In the cheat-webpages, one of them is to press 'L, R, Up and A' to select him and it says it unlocks his full moveset and secret outfit (long-sleeved), while the other is to press 'Up and C' to select him and it says it unlocks his second outfit (again), but nothing else. I have never played the game with anyone else other than Alucard, so now that i managed to get the game + emulator run well on my Win7 64x, i am going to give it a proper Richter and Maria thrashing, too! But Richter has two secrets on him. So many, that it truly pales in comparison against any other game, for the sheer number of hidden stuff, among other things. There are many secrets to this game, from giving a certain name to your new game profile after beating the game once, to doing certain things in-game to unlock secret areas (like the Alucart, not Alucard, items). And besides, there are many emulator fans around here, of this i am VERY certain! So i want to discuss about it, a bit. Discussing it from the past, i remember people here playing this game, or people generally infatuated with Sega Saturn in general.
